JVC RX-250 Service Manual

[YURIA1636]

I have the JVC RX-250 receiver, which malfunctions and makes noises when the volume is increased.

Does anyone in the forum have the service manual? What do you think is the problem?

I don't see the SM for the 250 but here is one for the 150..

Maybe it is similar enough?

I already have that, but I need it for the JVC SX-250 version

Pooping noise. I think because of dirty potentiometers.
